Abstract

La présente invention vise à fournir un dispositif d'affichage capable d'élargir la plage de perception d'une image spatiale lorsqu'un observateur perçoit l'image spatiale, et recréer une image ayant la même vivacité qu'un objet réel. Le dispositif d'affichage comprend : un dispositif d'affichage à cristaux liquides (LCD) (3) comme source de lumière ; une diode électroluminescente organique (DELO) (2) fonctionnant comme afficheur transmissif ; et un élément optique rétro-réfléchissant (1) qui rétro-réfléchit la lumière diffusée par le LCD (3) et amène la lumière rétro-réfléchie à passer à travers la DELO (2) de telle sorte que la lumière passée à travers la DELO (2) se concentre sur une région d'affichage spatiale rétro-réfléchissante (4). L'élément optique rétro-réfléchissant (1) affiche une image flottante (6) sur la région d'affichage rétro-réfléchissante (4), l'image flottante (6) étant une deuxième image correspondant à une première image qui est l'image d'origine (5) affichée sur le LCD (3). La DELO (2) affiche une image coordonnée (7) qui est une troisième image associée à l'image flottante (6) ou coordonnée avec cette dernière.
